To all whom, it may ooncem:

Be it known that I, Jnsrniz BLACKBURN, a citizen of the United States, and resident of St. Louis, and State of Missouri, have invented certain new and useful Improvements in Electric Attachments for Motor- Vehicles, of whichthe following is a specification containing a full, clear, and exact description, reference being had to accompanyin drawings, forming a part thereof.

y invention relates to certain new and useful improvements in electric attachments for motor vehicles, and has for its primary object, the employment of a switch box adapted to be carried in a fixed relation to.-

- the well known manner. On t is quadrant the steering column, and the location of the electrical conductors from the switch box entirely through and within the steering column, so that the switches controlling the various translating devices, such as the horn, lights and ignition, may be readily accessible to the operator.

' In the drawings,

Figure 1 is a top plan view of my invention applied in use.

. Fig. 2 is a transverse section taken through the steering column, steering post and the tubes mounted therein for control ling the gasolene andspark, and also the tube in whichthe electrical conductors are located.

Fig. 3 is a longitudinal vertical section taken through the switch box, the steering column and inclosed parts being shown in section and illustrating the conducting wires leading through the upper end of the steering columnfrom the switchbox and entirely l through the same, and passingout throng Yvices.

the lower end of the steering column.

Fi 4 is a diagrammatic view of the electrica circuit leading from the switches of the switch box to the various translating de- Referrin to the drawings, 5 indieates the I steering co umn, which is of the ordinary indicates the tube by means of which the gasolene is regulated, and 10 the hollow post for operating the spark apparatus. 11 in- H Specification Letters Patent. patentedgm 25,1921.

dicates a stationary tube'on which the quadrant, hereinafter referred to, is mounted, and located within this tube is the cable 12 carryingthe various electrical conductors13.

The tube 11 extends through the steering column from top to bottom and within this tube or casing are located the electric'alconrductors which pass entirely through ti steering column from the switch boigf out through the lower end of the same to he various translating devices.

1 1 'ndicates what is commerciallyknown as a quadrant, which is mounted on the tube 11 in the well known manner. Thisftube 1 1 is mounted within the steerin column in secured directly to the quadrant 14, and the.

arms 17 are securedto the quadrant and to the switch box. The switch box '15 is mounted above the quadrant, aswill be observe 5 from Fig. 3, so as to not interfere with the operation of the spark lever 19 and the gaso-j' lene lever 18.

The switch box 15 is fixed and immov l being carried by the stationary tubal-tori I which the quadrant, 14 is mounted. In the switch box 15 Iemploy a suitable numberof electric contact making and breakingde vices in the form of aswltch 21 whichhcontrols the lighting, a switch 22 for the horn,

and aswitch-23 for the ignition. In 1 the form shown, the switches 21 and .23areof' the-rotary type and the switch 22 is of the push button type. Of course, the-number of switches vemlployed degiends upon mea neber of trans ating de ces used.

In Fig, 4 I have illustrated dia, ;rainrnati cally, the different circuits, wherein-A 'i llustrates the main circuit, which iseonnected to the different switches. Light switch-21m connected so as to form the connection with the secondary circuit B, and when the switch is thrown on this circuit, the current will have to pass through the resistance coil C, dimming the light, and when the switch is thrown in the opposite direction C mplete the circuit D, the light is turned on in .full

force, the resistance coil .being out oiit. When the switch 23 is thrown onto-the wire E, the spark plug is thrown in circuit,

and when "the button 22 is pressed down, .the circuit leading to the horn is closed.

In otherwords, operating the switch 21 to the left, the current willipass from the battery through the wire A, into the i switch 21, thence through the'wire B into resistance coil C, thence into the lamp and back into the battery, making a complete I circuit.

When the switch '21 is thrown in the opposite directiomthe current will pass froin the wire A through the switch, into the wire D, through the lamp, into the battery, making a complete circuit. By pressin the button 22, the current passes from the attery into the wire A, thence to the button, returnin throu h thewire F'into the horn, and bac into t e battery, and moving the switch 23,

the current first passes through wire A,

through the switch, into wire E, and thence through the spark plug, and back into the "battery. a .As previously pointed out, the-switch box is stationary relative to thesteeringcolumn, being mounted on the quadrant, which is carried' by a stationary tube, located within device.

-' erate t thesteering column. quadrant may be said to be carriedindirectly by the steering column, or it may be said that the switch box 'mounted on the quadrant is carried by the steering column.

B the construction, as previously forth, it is obvious that I provide a simple :and efiicient device, which the driver may use without removing his hands from the steeringl wheel to electrically control and ope. horn, light and ignition, or any. "other translating device which may be used. The switch box being stationary, it is readily accessiblefor use, regardless of the position the steering wheel may assume.

By-immovably mounting the switch box and leading the electrical conductors from the switches within the switch box down and entirely through the steering column to the translating devices, it will be seen that regardless of the position of the steering wheel, the various translation devices are under the control of the driver at all times,

without the necessity of removin'gnhis hands ,from the steering wheel. Furthermore, such an arrangement thoroughly conceals and protects all the electrical. conductors,

and prevents them from being subjected to any stress or torsion in the operation of the Havin fully described my invention, what I c aim is:- g

1. In an electrical attachment for motor vehicles a steering post adapted to carry a steering wheel, a stationary conduit 1'- cated within said steering post, a quadrant mounted on said stationary conduit a switch box mounted on the upper en of In other words, the i set the stationary conduit. and secured to said quadrant, switches mounted in said switch box, and a series of electrical conductors secured to the switches and located within said stationary conduit.
